Teallwhpm it 'magi-comm:

Be; it known that I, CHART-.Es- B. SoHoEN- Mum, a.. citizen of the United States and lresident of Waterbury, inthe county of New Haveny and' State of Connecticut, have 1nventedi certain new and useful Improvements in Primary Batteries, of which; the oliow-r in `is a specification.

' y' invention relates to newv 'andi useful improvements in primary batteries employingl circular or annular forms offpositive and 'negative elements; and particularly to4 the construction and arrangement of such elements and means for supporting the same within the jar-by a single rod.

It isthe object of my mvent-on to provide a battery of this class. which wi-l'll be more eiiaient than thcsenow in use by reason of its'znovel eonstrnctionwhereby a larger area o' the annular negative element is 'made available; further to pronride a'novel. formef connection intermediate of the said elemeats whereby the same may be sus ended by Single rod: from theV cover of a battery jar. A

The several parts oiny battery including both thepositi-ve and negative elements .are soeonnected andsupported as to be capable of suspension from the. cover of a jar by a single rod,- and adapted to be attached to or detached from saidcover by a. single mit which, permits the` battery to. be removed veryqmcklyand con fenient.l v. v

The foregoing form of construction constitute's what -isnow known in the trade as an assembled element and while more or less common in the late formsof elements has not tomy knowledg dlicml or annular forms 'of solidified eloinents In lthis connection I have also .produced aconstruetion which will'permit of either the positive or negative c ornectifm for the'battery being made throughthe said eentral'swppo'rting rod and likewise for the 45 .opposite connection beingr made through a 'wire for connection wi-th the opposed element.

UponA the 'accompanying two sheets of' drawings form-ing a.- part of this specification similar characters of reference Adenote like 'or corresponding parts throughoutthe severalfglli'es `and 'of which, Fighe 1,.'--Shows a central` vertical. sections viewv through one dorm of my im- Fig. 2, is a dee been produced with cvlin-v shown in Fig., 1=. Fig. 3, is a central, vertical seetional' view through the said elements but connected ina slightly different manner andi whereby theY central rodv connection represents. the pole for the. positive ele- 'lnen'ts While the wirev is connected withV the negative element. Fig. 4., is a plany view of the end caps-241 shown in 1 and; 2 for supporting the nega-tive element, and'Fig. 5, is a plan view o-f the end: caps 24 shown in Fig. 3. for supporting the saine element.

eerrng in.. tletail to the characters of referenceniaf d upon the drawing's'l() indficates a jar its coreignnd 12 4and 13 holes in the'coverthrough which connections are-had with the elements of the basttery and by means off which said elements are sus# pendbd within the solution 1.4iv from the cover.

15 represents a threaded suspension Yrod or hangerwhich is designed to4 bepassed through they central hole. 12 of the cover and secured thereto by provi-ded with' bindingnuts 17,.-,wheeby a ltie-ld wire, not' shown, maybe attached for connection tothe one side of. the battery. The lower endof this rod is headed while the adjoining threaded end portion is -provided with a-nut 1'8 intermediate of which and the said head, Iis secured :i bridge strip 19 the opposite end. portions of which are ("onnectedby means of nuls 20 with verti- 1 callyv disposed Wires 2l.A which extend down aloneP theside-'of the cylindrical compressed negative element 22 4and passed through holes 255 in ,the end caps'24 arranged over the opposite ends of the said negative elements. 'Lhe"cylindrical negative electrode is preferably composed of'oxid of copper scale which is [irst finely ground and then pressed vintoA form. and baked lso form a soare formed. oizinc which may be either rolled and bent into 'foi-m,v or molded as preferred. l

fore mentioned connecting Wire 31. A further hole is formed in the central portion of :llindrical oxid of copper negative electrode,

the cross piece innnediatelv below the sus@ pension rod 15 and serves for theattachment of the second positive electrode 28 through the medium oi the stud 32 and nluts From the Jforegoing construction it will bt seen that the positive and negative elem-ents are positively insulated one from the other and are provided with a separate fielid connection, at the same time they {lare-all suspended from a single and centra ly disposed suspension rod. The particular arrangement of the elements with relation to each other, namely, one positive element snrrounding the cylindrical negative element and a Second positive element disposed centrally within said cylindrical. negative element, obviously insures a more ready action or attack upon both sides of the cylindrical negative element thus insuring a `battery of higher eciency than if it operated upon the one side only.

In Fig.v v3, Iliave' shown a construction wherein `the same principle is applied, though the connections for the'field wircsjare reversed, that is, .the posit-ive elements are for the positive elements.

. I claim and desire to vsecure by Letters Pata-cylindrical zinc electrically rconnected 'with the suspendingr -rod 151 while the Held Wire 31 is connected with thenegative clement In doing this vT dispense with the'bridge 19 and pass the rod- 151. through and attach it to the cross piece 251 in a way to also forma connect-ion for the zinc clement. 28, the upper 'end of which is tappeti to threadably engage the lower extremity of the said suspending rod. The negative element 22 isinsulatively connected with and supported fiom the cross piece 251 through the medium 'of the Wires 21-and nuts 20. The field wire 31 which in this `case forms the positive pole is connected throughth'e said wire with the negative electrode and the rod 15 forms the negative pole Having thus described my invention what entis .1. The combina-tion ofv a compressed cy lindrical oxid of copper negative-electrode,
